Former Republican presidential nominee Mitt RomneyWillard (Mitt) Mitt RomneyThe looming battle over Latino voters Arizona: On the fast track to swing state status Why Biden could actually win Texas MORE scoffed Monday at White House confidence that Democrats would curtail major losses on Election Day.

"They're gonna lose big time," Romney said in an afternoon interview on Fox News.


White House press secretary Josh Earnest told reporters Monday that President Obama agreed with Vice President Biden's remarks earlier in the day that Democrats would maintain control of the Senate.

Earnest said their confidence stemmed from voters wanting to support "a candidate who is fighting for policies that benefit middle-class families." He also applauded Democrats' ground game.

Romney said that the White House sees the same polls as everyone else, polls that illustrate Obama's low popularity.

The former Massachusetts governor, who has remained coy about whether he will launch a third White House bid, said Tuesday's election was the "last chance" for Americans to "pass judgment" on Obama's agenda. He noted turnout would make the difference.

"I do think that we're gonna pick up a lot of seats," Romney said, adding that gaining even a handful of Senate seats would show a "complete rejection of the Obama administration's agenda."

After the midterms, Romney said, the GOP needs "to show that we have ideas" on immigration, sealing the border and tax reform.

Romney has campaigned across the country for Republican congressional and gubernatorial candidates, repeatedly saying that he is not currently running for the White House nor planning to launch another bid.

"I'm hoping that my effort will pick up a few votes here or there," he said Monday when asked what that campaigning meant for his own prospects, quickly adding, "this is about 2014."
